Unusable – AsthmaMD Review

I just bought the AsthmaMD Lung Performance Peak Flow Meter with free tacking app. I downloaded the app but the app is unusable because it keeps asking me for a PSP code. Nowhere on the receipt, box, instructions or flow meter do I see a PSP code. What good is an app if I can’t even provide the mystery code it requires just to sign into it?
